TSP #248 - Zurich Instruments MFIA Impedance Analyzer (Z = 1mΩ - 1TΩ) Review, Teardown & Experiments
In this episode Shahriar reviews the Zurich Instruments MFIA Impedance analyzer. The unit is capable of measuring impedances from 1mΩ to 1TΩ and across a frequency range of 1mHz to 5MHz while providing a basic accuracy of 0.05%. However, this instrument is much more than just an Impedance Analyzer, it is build on a lock-in amplifier architecture with sophisticated capabilities and features:
